Disable the tick interrupt in tick_init(), which is called early in sparc64_init(), until the interrupt is enabled again in tick_start(), called by cpu_initclocks(), with our own handler. This fixes the hang during probing Sun keyboards on AXi boards and Ultra 10, with other machines like Ultra 5 probably being affected but not tested. END
